To @ZZ whom r't nntp/f concern,.-

Beit known that we, THEODOR KPPER and LAMBERT IPFER, citizens of the German Empire, residin at Aix-la-Chapelle, lthenish Prussia, Germany7 have invented -improvements in lWalls and lWall Plates or Slabs, of which the following is a specification.

Our present invention relates to improvements in walls and wall plates or slabs; and the objects of our improvements are, first, to provide a wall made ot plates or slabs each of which is connected with all surrounding slabs and supported by the same by means of oblique-crossed strutting-rafters made of connecting medium, thus producing a wall that is run through by means of a crossed channelnet continuously passing through the entire wall and filled up by connecting medium, and, second7 to provide means forarran-gingin the said channel-net one or several obliqueliron struts. lle attain these objects by the wall and plates illustrated in the aecompa ying drawings, in which- Figure l is the front view of a wall made ot plates or slabs. Fig. 2 is the cross-section oi' that wall. Fig. i?) represents the view of a single plate, and iinally Fig. et shows the longitudinal section of such a plate. r

Similar letters refer to similar parts throughout the several views.

The plate or slabp is provided at all its four corners with an obliquely-directed channel ca running 'from both bed-joints to both side joints. In order that those oblique channels are continued into the surrounding slabs, the distances of the ends of the channels from the corners of the plates are the ollowing: The oblique channels coming from the upper bedjoint, as well as those coming from the under bed-joint, terminate simultaneously in the middle of the side joints. The distance of the end of the channel in the bed-joint from the corners of the slab always is the fourth part ot the length of the slab. rlhe plates, preferably, are cut up at two corners diagonally opposite each other7 and that in such a way that the middle part of the triangle, the hypotenuse or" which forms the oblique channel c, is cut off, 3. The plates can be immediately cast so that they are provided with the aforesaidnotches fn.. Instead of arranging the notches a at two corners only we can provide the plate at all the four corners with notches. The said notches afford facilities for the proper mounting of walls made of such plates or slabs and containing in its interior one or several iron struts.

The wall is mounted as follows: Between the upper beam d and the under beam l) are arranged the iron struts s at an angle correspending to the oblique directon of the channels c. Thereafter we shove the plates p over the said struts, the notches of the plates embracing the iron struts s, Fig. l. After having the plates mounted in this manner We cast the connecting material into the channels c.

By means ot' our plates it is possible to mount a wall in the interior of which are contained one or several oblique iron struts, and we can do so without being obliged to hew the plates in any way. Each plate is connected with all surrounding1 plates by means of eight rods made of connecting mediumtwo in each bed-joint and two crossed rods in each side joint. Finally each plate is supported by means of strutting-rafters made of connecting medium and with two rafters from below and one at both sides.

'Ve are aware that prior to our invention plates or slabs have been made with channels and walls have been constructed of such plates and containing iron rods. We therefore do not claim such walls and plates broadly; but

W'hat we do claim as our invention5 and desire to secure by Letters Patent, is-- l. A wall plate or slab provided at its four corners with oblique channels extending each from the horizontal bed sides to the middle of the vertical sides of the slab, the ends of the channels in the bed sides being distant from the corners about the fourth part of the length of the slab7 essentially as set forth and for the purpose speciiied.

2. A wall plate or slab provided at its four corners with oblique channels extending each from the horizontal bed sides to the middle of the vertical sides of the slab, the ends of the channels in the bed sides being distant from the corners about the fourth part of the length of the slab, the said slab being provided at two diagonally opposite corners with notches extending from the corner to the said ranged in the said notches and in the said oblique channel, essentially as set forth and channels, all essentially as described and for for the purpose specified. the purpose specified.
